The price of Bitcoin now is very appealing, considering that the price of $6,600 last year was reached at the last quarter of 2017 then it started to crawl up to $19,500. If all happens the same just like last year, then $20,000 USD is just a piece of cake. But consider selling a portion of your profits when you reached a goal to secure your profits and keep some in case price continue to go up.
Generally, if you want to do well in any financial investment decisions, just do exactly the opposite of what you see the market doing or generally what you see others doing.
When they are selling and the panic is getting huge with a lot of FUD and drop down in the market, start thinking of buying and when you start seeing some buying spree, greed and a lot of people beginning to call moon, you really do not want to be holding much on any market in this time and this is when it is always expected for anyone to sell.
Being a contrarian trader can pay off but only if you are very good at it, because you are going to try to predict when the current trend is going to end something that is very difficult to do, but if you can do it then you can make a lot of money, just remember that such a strategy is very risky because if the markets do not follow your prediction you could lose almost all your money.
